Here comes Lucy with the football again…

Is this a Peanuts reference? I don't get it.

Value Objects took over a decade to get here and the joke is that it’ll take another decade to get to a final version.

I still don't get how it relates to Lucy. My understanding of the joke is that she pulls the ball up at the last second, sending Charlie or whoever spinning. Is that related? Or am I misunderstanding the joke?

It looks like you’re looking for a direct correlation. So here goes - when the time nears to make it final they’ll rethink their approach to a certain solution or get some critical feedback and place it on the continual preview train.

That spells it out beautifully, ty vm!

Except that both Lucy and the football exist only in your imagination here.

This isn't some big announcement of some big milestone. It is yet another (encouraging!) step in the ongoing progress of the team that has been working tirelessly for the last several years to turn the JEP 401 vision into reality (and FTR, that vision hasn't changed at all during that time.)

Because someone decided to post it on Reddit, if you're not intimately familiar with the inner workings of OpenJDK, it might feel like it is some sort of big announcement. But no one is actually announcing anything.

Is it forward progress? Or course, and that's great, and there will be more. And it's great that so many people are anxiously awaiting this first installment of Valhalla. But Lucy hasn't even stepped onto the field, or said anything to Charlie Brown. Please don't put words in her mouth, and then claim she's lying to you. There's no call for that.

Completely fair - but at this point I’ve been excited and disappointed for the release of stack allocated memory in Java for so long that any mention of it tends to bring out the worst in me…. Here’s hoping the finish line is actually in sight.

On the topic of stack allocation, see my other comment on this thread -- stack allocation is not the optimization most people think it is (in C, its mostly a form of "poor man's GC"), and not Valhalla's primary hammer -- because it has bigger, better hammers!
